GEORGE MATTA, OF BRADDOGK, PENNSYLVANI'A'.

ANTIFRICTION-BEARING.

To uili whom it may concem:

Be it kIIOWIl that I, GEORGE MATTA. a subject 'of the King of Hungary, residing at Braddock, in the county of Allegheny and Another object of the invention is to utilize rollers and balls for contacting bearing surfaces, said rollers and balls being arranged to rovide a simple and durable structurehavmg elements easily and quickly assembled.

A further object ofthe invent-ion is to pro vide a bearing that can .be economically and advanta eous y used in connection with vehicles, a though the same is applicable to various kinds of machinery. I

With theabove and other objects in view, which will readily appear as the invention is better understood, the same consists'in the novel. construction, combination and arran ement of: parts to be hereinafter d'escri d, and then specifically pointed' out in side elevation of a detached housing forming the ap ended. claims.-

In' t e drawings, Figure 1 is a longitudinal sectional view of a bearing'constructed in accordance with my invention, Fig. 2 is a apart of the bearing, said housing being partly broken away.--

- In the accompanying drawings 1 designates a cylindrical hub or casing upon which i is mounted cylindrical spoke or web suporting members 2; In the hub 1 intermediate the ends thereof is mounted a cylindrical rtition 3, and extendin longitudinally t rough saidfpartition an the huh I 1s a spindle 4- of an axle 5. Revolu'bly mounted upon the spindle 4 is a sleeve 6.

Circumferentiallg of the sleeve '6 and bearing directly t ereon are aplurality of rollers 7 of a less length than the hub l'and corresponding in length to the sleeve 6. Each roller adjacent to the end thereof is provided with-a ball race or annular groove 8.fo'r anti-frictional balls 9, said balls being retained within the races 8 by sectional Specification of Letters Patent. Application filed June15, 1908 Serial No. 438.540.

a cap Patented Feb. 23, 1909.

semi-cylindrical casings, each casingcomprising sections 10 and 11, the section 11 bemg threaded within the section 10, as at 12.

The inner end of the hub 1 is closed by two plates 13 having anti-friction balls 14 arranged therehetween. These plates are inter osed between the ends of the rollers 7 an a collar 15'mountedu on the axle 5. The opposite end of the ub is closed by a housing 17 mounted u on the hub 1 and the spindle 4 of. the a e. The housing 17 is formed with a central sleeve 18 and with a conical bearing surface19 for a plurality of circumferentially arranged conlcal rollers 20 havi11 contacting collars 21 and 22. The conic rollers are retained in, osition by interior rings 23 and 24, the ormer being threaded in the housing and the latter threaded upon the sleeve 1-8 within the housing; interposed between the rin s 23 and Z4 andth'e rollers 20 are an ifriction balls 25.

By reference to Fig. 1 of'the drawings it will be observedthat the outer end of the I hub 1 is beveled at 26 and contactswith the conical rollers 20 toreceive and reduce the "friction set up by an end-thrust action.

The housing 17 is retained in position by or nut 27 threaded upon the outer end of the axle spindle 4.

vIt is apparent from the novel construction of my bearings that I have devised a hub that can be readily usedfor the wheels ofheavy vehicles'particularly those for convey ingbheavy loads. Thewearin parts ofthe hu are made of harde'nedstee and with the use of a suitable lubricant, the various elements of my bearing insure easy running.

While in the drawing forming a part of this application there is illustrated the preferred em odiments of my in'ventiomit is to be understood that the elementstherein can be variedor changed as to shape, proportion and exact manner of assemblage without departing from the spirit of the invention;

- Having now described my invention what I claim as new, is -.1

1. In an anti-friction bearing, the combination with an axle spindle, a cylindrical hub surrounding said spindle, plates closing the inner end of said hub, ant1 friction balls arranged between said lates, a housing fitting and provided with an inwardly extendin sleeve formed with peripheral threads, sai

rollers within said housing for engagingthe end of said hub, peripherally threaded rings U mation with a spindle, of a cy drical hub the threads of the housing whereby said rings are connected to the housing, anti-friction balls inter osed between said rings and said conical ro ers, and means for retaining said housing upon said spindle and said hub,

2. In an anti-friction bearing, the coinbination with a spindle, of ahu-b surrounding said s indle, plates for closing the inner end of said hub, a housing fitting provided with an inwardly extending sleeve fitted upon the outer end of said hub and upon said spindle, saidsleeve provided with peripheral threads and said housin having" interiorly arranged threads, circum erentiaIl arranged conical rollers within said housing for bearing upon the outer end of said hub, rneans engaging with the threads of the sleeve and threads of the 'hous' and provided with groo'ves to constitute all. races, ballsmounted in said races and engaging the rollers, and means for retaining said conical rollers within said housing. 7 r v 3.' In an anti-fiiction'bearin theeombisurrounding said s indie, said "huh having one end beveled, a ousi11g fitting upon the engaging with the threads of the sleevean d.

outer end of said hub and said spindle, conieal rollers arranged in the housing for bearing against the beveled end of said hub, and means bearing against the other end of the hub for retaining said housing upon the hub, and means for closing the inner end of the hub.

4-. In an anti-friction bearing, the combinationwith a spindle, of a cylindrical hub surroundin said s indle a hoilsin -fittiiig u )on a 7 B i the outer end of said hub and provided with an 1nwardly pro ecting sleeve fitted upon said spindle, conical rollers arranged in said housing for bearing against said "hub, hear- -1ng means carried by the sleeve and engaging the inner ends of said rollers, and means for closing the inner end of said huh.

5. In an anti-friction bearing, the combination with a spindle, of a hubinclosing said spindle, said hub having one'end beveled and constituting a bearing, a housing fitting upon.-
